Effect of experimental PVR and RD on amplification of retinal prepro-ET-1, ETR-B, and GADPDH mRNA sequences. Extracts were prepared 3 days after each procedure. Intensity of the prepro-ET-1 and ETR-B amplification products increased after experimental PVR and RD. Both bands were always stronger after RD than after PVR. Intensity of the GAPDH amplification product did not change significantly.
